		PropertyValueProvider<MyPersistentProperty> valueProvider, PersistentPropertyAccessor<?> accessor) {

	for (MyPersistentProperty prop : persistentEntity) {

		if (prop.isAssociation() && !persistentEntity.isConstructorArgument(prop)) {
			continue;
		}

		// We skip the id property since it was already set

		if (persistentEntity.isIdProperty(prop)) {
			continue;
		}

		if (persistentEntity.isConstructorArgument(prop) || !data.containsKey(persistentEntity.getName())) {
			continue;
		}

		accessor.setProperty(prop, valueProvider.getPropertyValue(prop));
	}
